Replace /strI- with /iyaG before vowels.
As /strI- is a /nadI (by !! ), it should work before vowels like **nadyA नद्या and **vadhvA वध्वा (by !! ,notsure) with no << aciznudhAt.... This is an exception in advance to << aciznudhAt....
/strI- + /TA → !**striyA स्त्रिया
/strI- + /Ge → **striyai स्त्रियै
/strI- + /au → !**striyau स्त्रियौ
/strI- + /jas → !**striyas स्त्रियस्
But not before /Am, because hrasvanadyAp... has precedence over this rule (by vipratiSedh...) and makes /Am into /nAm, which starts with a consonant —
/strI- + /Am
→ /strI- + /nAm by hrasvanadyAp...
→ !**strINAm स्त्रीणाम्, with /Natvam
